Explore shell science!

Malacology is the study of mollusks - invertebrate creatures with soft, unsegmented bodies, many of which house themselves in shells. This fascinating and highly diverse group of animals includes more than 100,000 species, ranging in size from snails so small that we can barely see them to giant squids more than 60 feet long.

The Strake Hall of Malacology highlights these creatures through models, fossils, dioramas, living specimens, and hundreds of rare and spectacular shells.
